Thanks but that point was reached some time ago. Just booting and
operation was blind (or serial only). Not really a full potential.

Yeeloong chip is soldered, except in dev models. While flashing is
equally easy on both of them (flashrom -w grub.img), recovery from a
failed flash on yeeloong isn't. Solution would be to distribute compiled
and checked versions of flash. It's somewhat "one size fits all"
compared to the customization possibilities of self-created GRUB but is
much safer. My proposition for precompiled ones to support msdos and
GPT, btrfs, xfs, ext*, fat, ufs2 and zfs (+ntfs if size permits, useful
for external drives), linux and kfreebsd, simultaneous console on local
(US keylayout) and serial , jpg for background, filled with other useful
modules up to 512K.  It would wait for 2 seconds for user to press ESC,
if he doesn't it loads the first ($part)/boot/grub/grub.cfg or
($part)/grub/grub.cfg it can find. I can post the configline for this
and/or compiled image but I'm not able to check it before June, 20 when
I'll be back in Europe. If someone can test it earlier we can distribute
it earlier.
OTOH Yeeloong liberation isn't done yet. The problem is EC. We have no
free EC firmware (it's on separate chip than normal firmware) available.
Reinder de Haan is working on it but it's a very difficult task.
